IMPROVEMENT IN CULTIVATORS;

Specification forming part of Letters Patent No. 24,514, dated June 21, 1859.

To all whom it may concern:

Be it known that I, HENRY WELLs, of Walnut Grove, in the county of Knox and State of Illinois, have invented a new and useful Improvement in Cultivator-Flows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which- Figure l isa side sectional elevation of myiuvention, taken in the line 00 :20, Fig. 2. Fig. 2 is a back view of the same. Fig. 3 is a horizontal section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the beam of theplow, constructed in the usual way.

B B are handles, attached to the back part of the beam; and U is an inclined bar, which is attached to the back part of the beam, a traverse bar, a, which connects thetwo haudles, passing through the upper part of bar 0.

I) is a eolter, the upper end of which is of cylindrical form, and has a screw-thread cut or formed on it. y This cylindrical part passes through the beam A, and has a nut, E, on its upper end.

To the lower part of the colter Da share, F, is attached, ofdouble formthat is to say, having two inclined sides, I) I), which converge to apoint, as shown clearly in Fig. 3.

G G are two wings or mold-boards, the outer sides or surfaces of which are inclined as desired. The front ends of the wings or moldboards are each provided with a lip or te'non, c, which are fitted one over the other and both placed in a recess in the back part of the body of the share, and a pin, 0, passes vertically through the share F and lips and tenons 0.

By this mode of attaching the wings or moldboards to the share a joint is formed which admits of the ready adjustment of the wings or mold-boards, so that they may be expanded or contracted to form a furrow of greater or less width, as desired. The bottoms of the wings or mold-boards and share are in the same horizontal plane.

To the inner side of each wing or mold-board ahorizontal curved rod, H, is attached, and these rods pass through the lower part of the bar G and are allowed to slide freely back and forth on said bar, the rods being secured at any desired point, when necessary, by means of keys, set-screws, or any suitable device.

To the upper surface of each wing or moldboard G a vertical rod, I, is attached. The upper parts of these rods have horizontal parts 01 cl attached; or the rods 1 may be made sufficiently long to allow of their upper parts being bent in horizontal positions and curved precisely similar to the rods H. The parts d d of the rods 1 I pass through the back part of the beam A, and may be secured at any desired point by keys or set-screws, like the rods H. The rods H H cl (I serve as guides and supports to the wings or mold-boards G G and keep them perfectly firm and steady, preventing all torsional strain and racking to which said parts are subject a s usually constructed and arranged.

The method of jointing the wings or mold together and to the share forms a firm connection, and the plow as a whole is rendered perfectly firm and stiff, and still the wings or moldboards rendered capable of being adjusted with the greatest facility.

I am aware that cultivator-plows have been previously constructed in which expanding wings or mold-boards have been used, and I therefore do not claim broadly such device; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

This arrangementofthe share F, mold-boards G G, rods H H and I T, the latter having the parts (1 d formed on them, and said parts passing respectively through the bar 0 and beam A, thus making a very firm structure, in the manner and for the purpose set forth.

HENRY WELLS.
